Found this post from Fried Reim on a German hi-fi forum. It’s from early April, translated by google:
“For the occasion, I would like to point out our new headphone amplifier + D / A converter.
The Violectric V590 is the first of a series of new Violectric devices that will appear at irregular intervals.
The first prototypes were shown at previous trade fairs, series devices should be available from Hi-End 2020.
Well, the hi-end is canceled and we are presenting our new devices in some forums.
The backgrounds.
Not only we, but also our customers are convinced of our so-called "V200" amplifier technology. Since the development of the HPA V200 in 2009, it has offered a rather warm sound, which is unusual for transistor technology, and can therefore handle height-emphasized headphones quite well.
We have also been convinced of symmetrical headphone amplifiers since we developed the first German headphone amplifier manufactured in series in 2010.
That was the HPA V181.
The combination of "V200" technology and a symmetrical headphone amplifier became the HPA 281, which was launched in 2014.
It reached sporty sales figures for our standards and is the most noticed German thread at Head-Fi with 600,000 clicks.
We continue to develop and sell D / A converters very successfully.
The DAC V850 offers adjustable resampling and dual mono converter (2 x PCM 1795).
It also has a USB input which, however, cannot do a DSD because I am an avowed DSD hater ...
So it was only natural to replace the V281 after 6 years of production and immediately install an "adult" D / A converter - because it's from the customer is required.
The aim of the development was to sharpen the valued properties of the V281 and to add a D / A converter.
That is why the V590 naturally has 4 amplifiers for a real balanced headphone output.
This includes analog and digital inputs and of course a preamplifier function with sym and unsym. Line outputs.
Further generous possibilities of level adjustment, because the KHV does not know by itself which source is connected to the front, how sensitive the headphones are and which level the power amplifier or the active speakers prefer.”
